To all whom itmay concern:

Be it known that I, THOMAS S. BENNE'I'I, a citizen of the United States, residing at Attleboro, in the county ofBristol and State of Massachusetts, have invented certain new and useful Improvements in Bands for Bracelets, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to that class of bands for bracelets which are of the lazy tongs type and is an improvement of the structure set forth in my former United States Patent No. 709,195. V The essential objects of my present'invention are .to produce a more firm, secure, and cheap union of the parts which shall have a sightly appearance; and to form the back side of the band in such a manner as produce a smooth, unbroken surface. The rear surface of bands as at present made have joints into which the perspiration from the arm penetrates and soils the gold, and in case of gold plated goods, coacts with the brass to stain the gold and flesh.

To the end of securing the enumerated advantages, my invention consists in the novel construction and combination of parts hereinafter set forth, and illustrated in the accompanying drawings, wherein,

Figures 1 and 2 are rear and side elevations tively of a front arm shell. Figs. 3, 4 and 5, side elevations, of the parts inclosed within a front arm. Fig. 6, a rear elevationof a complete front arm. Figs. 7 and 8, rear'and side elevations respectively of a back arm shell. Fig. 9, a side elevation of rear plate of a back arm. Fig. 10, a like elevation of one of the back arm plates. Fig. 11, a rear elevation of a complete back arm. Figs. 12 and 13 are rear and side elevations respectively of a complete unit. Figs. 14 and 15, sections of the same on lines x a: and y g respectively 'of Fig. 13. Fig. 16, an elevation of the rear of the novel band complete, and Fig. 17, an elevation of the rear of the old form of band.

Like reference characters indicate like parts throughout the views.

A convenient embodiment of my novel band comprises a plurality of units, arranged in a lazy tongs series, each unit comprising a front arm, A, and back arm, B, pivoted to each other at their centers. These arms may inclose springs as hereinafter set forth, or

, the springs may be located outside the arms as shown in United States Patent No. 782,188, it being immaterial to the purposes of this invention what, if any, spring mechanism is employed. A

The arm, A, comprises a shell or cover, a, cupped up from a thin metal blank of precious or plated metal, having its inner margin cut away to form a flange, a, and shoulder, a Upon oppositesides of the shell, a, the flange, a, is transversely cut or sawed at two points as a thereby producingindependent flange portions,

' serted inthe shell, a; said respec a opposite each other midway the length of the shell.

When the spring means of my former patent is used in the arm, A, the arched plate, C, shown in Fig. 3 is inplate being provided with the notch, c, and carrying the tubular pivot, c. The plate, 0, rests against the back plate, D, shown in Fig. 4. The latter is provided with tubular rivets, d, upon its end with which to pivot the front of one unit to the back aim of the adjacent unit. The plate, D, has also an opening formed by a collar, d, midway its length, through which passes'the pivot, c, and .a spiral spring, ters in the notch, c, and whose other'end, e, extends within the back arm. The back or retaining plate, D, is held in position by bending over upon its margin the flanges, a, as shown in- Fig. 6. The flange, a, is

folded inwardly upon itself with its edge resting upon.

- ears, a, are concealed by the back arm now to be described.

The back arm, B, comprises a shell, b, of plated stock, provided with a flange, b, shoulder b and ears I), produced by cuts, b all similar to the corresponding parts of the shell, a. A plate, F, shown in Fig. 10 provided in its ends and center with rivet 30 engage the rivets, d, and pivot, c, is placed within the shell, 6. The back or retaining plate, G, of the back arm is shown in Fig. 9. It is provided with a central opening, 9, iiito which passes loosely the sleeve, d, and this opening is preferably surrounded by a tubular extension, g. The plate, G, has also an integral marginal flange, g which may be omitted if the stock of the plate is thick, and end perforations, 9 The plate, G, isfixed inposition by. pressing the ears, b, inwardly and downwardly upon its margin. The flange, b is folded upon itself, as shown in Fig. 15, with its edge resting upon the shoulder, b. In assemends of the E, one of whose ends, e, regisopenings,

'bling the parts the end, e, of the spring, extends within the arm B shell, b.

The assembled units, as shown in Fig. 16, present an unbroken surface to the flesh, and thus avoids the and presses againstthe side wall of the disadvantages inherent in old seamed structure shown I in Fig. 17.

The spring, E, it should be understood, is' omitted in a .majority of the units.

What I claim is,

a back arm provided with means for receiving said pivots.

2. A laz'y'tongs band composed of pairs of arms pivoted to each other at or near their centers, each pair of arms.

comprising first, a front arm provided with pivots upon its ends, and second, a back arm comprising a plate adapt ed to receive the pivots, and having an intermediate opening, an outside shell provided with a marginal flange folded upon itself, and ears upon the shell engaging the plate.

3. A lazy-tongs band composed of pairs of arms pivoted to each other at or near their centers, each pair of arms comprising first, a front arm comprising a plate provided with pivots upon its ends and an intermediate opening, an outside shell provided with a marginal flange folded upon itself ears open the shell engaging the plate, and second, a hack arm comprising a plate adapted to receive the pivots a hd having, an intermediate opening, an outside shell prov'ided with a marginal flange folded upon itself, and ears upon the shell engaging the plate.

In testimony whereof I have dfllxed my signature in presence of two witnesses.
